5.3.5.2 Operating mode
The operating mode determines the process sequence controlled by the welding torch. Detailed descripti-
ons of the operating modes

5.3.6 Welding type
Different forms of MIG/MAG processes are collectively referred to as welding type.
Standard (welding with standard arc)
Depending on the set combination of wire feed speed and arc voltage, the arc types short arc, transitional
arc or spray arc can be used for welding.
Pulse (welding with pulsed arc)
A selective change in the welding current generates current pulses in the arc, which lead to a 1 drop per
pulse of material transfer. The result is an almost spatter-free process, suitable for welding of all materi-
als, in particular high-alloy CrNi steels or aluminium.

5.3.7 Welding power (operating point)
The welding power is adjusted according to the principle of one-knob operation. The user can set their
operating point optionally as wire feed speed, welding current or material thickness. The optimum welding
voltage for the operating point is calculated and set by the welding machine. If necessary, the user can
correct this welding voltage
